Abstract
A free-drifting buoy system for maing measurements of magnetic micropulsations in the deep ocean is described. A spar buoy system is used to provide a stable platform in low to moderate sea states. The magnetic sensor, suspended 75 to 500 feet below the surface, is an optically-pumped Rb vapour magnetometer with a sensitivity of about 0.02 nT in the micropulsation band. Measurements of swell and wave activity are made using an accelerometer, a pressure transducer, and a capacitive wave pole.
